Arsenal fans have grown frustrated with their side's inability to challenge for the Premier League title, with the sales of Cesc Fabregas, Samir Nasri and Robin van Persie among others causing unrest.

Wenger has brought in Santi Cazorla and Lukas Podolski this year, with both established international-class players, but many feel the Frenchman could have done more to bolster his squad.

However, Wilshere - on his way back to full fitness following over a year out through injury - believes Wenger has done well in his transfer dealings.

"It is strange because last time I played was with Cesc Fabregas, Samir Nasri, Alex Song and Robin van Persie," England international Wilshere told Arsenal Player. "Now there's the likes of Podolski, (Olivier) Giroud, Cazorla and Mikel Arteta.

"The boss has done excellently. He's bought well. These players are proper footballers - they understand the game and they've been around.

"You look at someone like Lukas Podolski, he's got over 100 caps for his country.

"They're top players and it's easy to come into a team where they understand football so well.

"To play with someone like Santi Cazorla is so easy. He understands football, even little things like the pace of the pass he gives you, and his movement is outstanding."
